Specification of Letters Patent.

Patented Oct. 10, 1905.

Original application filed April 20, 1904, Serial No. 20,052v Divided and this appli eation filed MeyZZ, 1905. iSerial No 2619458.

To (1J2 who/at it 'nmg concern:

Be it known that l, EnNs'r J. Brine, a citizen of the-United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful improvements in Automobiles, of which the fol lowing is a specification.

This application is a division of my former application, Serial No. 20%,052, liled April 20, Wild.

My invention relates to self-propelled vehicles, and has especial reference to that class of vehicle propelled by electric motors supplied with current from a generator driven by an iuternal-coml nistion engine.

'llhe object of my invention is to provide n'ieans for deriving from the generator itself a voltage for use with the spark-coil of an internalcombustion engine, thereby rendering it unnecessary to keep a battery in constant use during the operation of the vehicle. 1

accomplish this result by providing the generator with an auxiliary brush displaced by a small amount from one of the main brushes and supplying the ignition device from the anxiliar,\ brush and the adjacent main brush. A voltage is thus supplied to the ignition device which may be of any desired amount suitable for the purpose and may be any fraction of the full voltage of the generator.

My invention will best be understood by reference to the accompanying drawing, whichshows diagrammatically electric motors suppliednvith current from a generator driven by an internal combustion engine arranged in accordance with my invention.

in vthe drmvimg, E represents an internalcombustion engine of any well-known type, which carries on its shaft the armature of an electric generator G. This generator supplies current from its main brushes 1) I) through a suitable controllin -switch (J to the motors M, which drive the vehicle. it will be seen that the generator G, in addition to the main brushes 1 /1, has an auxiliary brush b, displaced by a comparatively small angle from one of the brushes 117 A circuit is completed from a main brush 0 to brush (1 through the primary winding of the induction or spark coil 1 and through the. makc-and-break switch N on the engine-shaft. The secondary winding of the ind uction-coil IV is connected in the usual manner to the spark-ping P on the engine.

By using this auxiliary brush 1 am enabled to obtain a fraction of the terminal voltage of the generator suitable for use with the induction-coil I, and thereby to do away with the necessity of keeping-a battery in.oporation throughout the operation of the vehicle.

It will be understood that I have illustrated my invention diagrammatically and that in practice any well-known type of apparatus may be employed.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In combination, an internal-combustion engine an electric-generator,driven thereby, an electrical ignition device for the engine, and means for connecting said ignition device to points on the generator commutator having a difi'erence of potential equal to only a fraction of the terminal voltage of the generator.

2. in combination, an internal-combustion engine, an electric generator driven thereby provided with an auxiliary brush displaced a small amount from a main brush, and an electrical ignition device for said engine supplied from'said auxiliary brush and an adjacent main brush.

3. in a self-propelled vehicle, an internalcombnstion engine, an electric 'gcnerator driven thereby provided with an auxiliary brush displaced a small amount from a main brush, and a spark-coil for said engine having its primary connected between said main brush and said auxiliary brush. 7
